   There are some known problems with the ServerWorks LE chipset that
cause filesystem corruption on some recent kernels.  The bottom line is
that it appears to be a BIOS bug, and that disabling DMA on your IDE
chains will prevent that.  A chain of BIOS updates may or may not solve
your problem, but I haven't seen anything too encouraging yet.  A detailed
bug report can be found at

Good luck.
